Fully Hosted Solution
Shopify handles hosting, security, SSL, and infrastructure. Merchants focus on selling, not server management. Apps plug into a stable, always-available platform with guaranteed uptime.
Shopify App Store
Shopify App Development
I build custom Shopify apps, workflow automations, and storefront enhancements that help merchants scale their businesses. Modern JavaScript, Node.js, and the Shopify API - engineered for reliability and performance.
Why Shopify
A platform built for growth
Shopify powers millions of merchants worldwide. Its hosted infrastructure, extensive ecosystem, and the Shopify App Store make it one of the most accessible and scalable e-commerce platforms available.
Massive Ecosystem
Over 8,000 apps in the Shopify App Store, hundreds of themes, and a global community of developers. Shopify's ecosystem gives merchants the flexibility to build exactly the store they need.
Shopify App Store
The Shopify App Store provides a distribution channel that puts your app in front of millions of merchants. Built-in billing, reviews, and discovery make it the go-to marketplace for extending Shopify functionality.
What I Build for Shopify
Apps and integrations that solve real problems
From custom apps to headless commerce, I build Shopify solutions that fit your business - not the other way around.
Custom Shopify Apps
Bespoke apps tailored to specific merchant needs. Whether it's a private app for internal use or a public app for the Shopify App Store, I build it from the ground up with clean architecture and maintainable code.
Workflow Automation
Automated order processing, inventory synchronization, fulfillment logic, and notifications. I build integrations that remove manual steps and let your operations run on autopilot.
Theme Extensions
Theme app extensions that integrate seamlessly with any Shopify theme. Custom blocks, app embeds, and dynamic sections that merchants can configure without touching code.
Shopify Flow Integrations
Custom triggers, conditions, and actions for Shopify Flow. Automate complex business logic across your store - from loyalty programs to fraud detection to dynamic pricing rules.
Storefront Enhancements
Custom product configurators, dynamic pricing displays, advanced search and filtering, upsell widgets, and interactive storefront features that improve conversion rates.
Headless Commerce via Storefront API
Decoupled storefront architectures using the Shopify Storefront API. React-based frontends, custom checkout experiences, and multi-channel commerce with Shopify as the backend engine.
Technology Stack
Built with the right tools for Shopify
Every Shopify app I build uses modern, battle-tested technologies that align with Shopify's own recommended development stack.
JavaScript
The foundation of modern Shopify app development. ES6+, async patterns, and clean modular code for both frontend and backend.
Node.js
Server-side runtime for Shopify apps. Express-based backends, webhook handlers, background jobs, and Shopify session management.
React
Shopify Polaris components and custom React interfaces for app admin panels. Fast, accessible, and consistent with the Shopify admin experience.
Shopify API
REST Admin API and Storefront API for product, order, and customer management. OAuth authentication, webhooks, and rate-limit-aware request handling.
Shopify CLI
Scaffolding, local development, theme previews, and app deployment via the official Shopify CLI. Streamlined developer workflow from first line to production.
Liquid
Shopify's templating language for storefronts. Custom sections, snippets, and dynamic content rendering. Theme app extensions that work across all Shopify themes.
GraphQL
Shopify's GraphQL Admin API for efficient, precise data queries. Mutations for bulk operations, metafield management, and complex data relationships.
Development Process
From concept to the Shopify App Store
A structured, transparent process that delivers reliable Shopify apps on time. No surprises, no scope creep.
01
Discovery & Scoping
We start by understanding your business needs, target merchants, and the problem your app needs to solve. I define the technical scope, identify Shopify API requirements, and outline the architecture before writing a single line of code.
02
Architecture & Design
I design the app's data model, plan webhook handlers, map out the OAuth flow, and structure the codebase for maintainability. For apps with an admin UI, I prototype the interface using Shopify Polaris components.
03
Development & Testing
Iterative development with regular check-ins. Every feature is built with error handling, rate-limit awareness, and edge-case coverage. I test against Shopify's development stores and verify webhook reliability before moving forward.
04
Review & Deployment
Final QA, performance testing, and security review. For public apps, I handle the Shopify App Store submission process, including listing copy, screenshots, and compliance with Shopify's review guidelines. For private apps, I deploy directly to your store.
05
Maintenance & Support
Post-launch monitoring, bug fixes, and ongoing updates. I keep apps compatible with Shopify platform updates, handle API version migrations, and add new features as your business evolves.

FAQ
Shopify app development questions answered
Do you build public or private Shopify apps?
Both. I build public apps for the Shopify App Store that serve a broad merchant audience, as well as private custom apps tailored to a single store's specific needs. Public apps go through Shopify's review process, while private apps are deployed directly to your store for immediate use.
Can you integrate my Shopify store with external services?
Yes. I build custom integrations between Shopify and ERPs, CRMs, accounting software, fulfillment services, and any system with an API. Using Shopify's webhooks, the Admin API, and background jobs, I ensure reliable, real-time data synchronization between your store and external platforms.
Do you work with Shopify Plus?
Yes. I have experience building apps and customizations for Shopify Plus stores, including checkout.liquid customizations (now Checkout Extensibility), Shopify Scripts, Shopify Flow integrations, and multi-store setups. Plus features like exclusive APIs and higher rate limits are fully leveraged.
How do you handle Shopify API versioning?
Shopify releases new API versions quarterly and deprecates old ones on a predictable schedule. I proactively migrate apps to the latest stable API version before deprecation deadlines, test against release candidates, and ensure backward compatibility. This prevents disruption and keeps your app running smoothly.
